If you're talking about the Bekant, I have that too and am comfortable using it. I am 6'2". I keep the desk surface such that my elbows are about 90 degrees while resting on it. I have a monitor arm that puts the center of my screens about 18" above the desk surface. If you're trying to use a laptop sitting flat on the desk while standing, that is going to be uncomfortable at any height because your eyes and hands/arms need to be further apart.
